Oil pump priming. Vaseline needed?

IMO, both Vasoline and Lubriplate are both too thick. I have seen Lubriplate stop an oil pump from picking up prime, first hand. Vasoline is even thicker. Prime the oil pump with what it was intended to pump. MOTOR OIL.

Now, I would endorse disassembling the pump, which you should do anyway to check and correct clearances, and putting a THIN FILM of Vasoline as an initial lubricant. There would be nothing wrong with THAT. But to prime it totally with Vasoline.......eh......no.
